Datum Management in Esri’s Collector app vs. Trimble’s TerraFlex

Due to the recent interest in our Collector vs. TerraFlex Webinar, I think it’s time we address datum management, both horizontal and vertical.  High accuracy in either software is now attainable.  3D accuracy allows for not only excellent XY values, but also, highly accurate Z values. Datum management to avoid datum shifts is not difficult, […]

The Trimble TDC100 runs the Android OS, so it’s important that before you begin, make sure to get the Geode Connect App from the Play Store.   This app allows you to configure the settings inside the Geode.  Here are the recommended settings: Turn on the Juniper Systems Geode On the TDC100, tap the Menu […]

Work or Play? Mapping Baseball Fields with Laser Technology

It’s not every day one gets to spend on home plate at AT&T Park where the San Francisco Giants play baseball in front of thousands of spectators at the field and millions watching on TV. When a client came to Elecdata asking for a more efficient and accurate way to map assets and features surrounding […]

Field to Aerial – Closing the Loop

It’s critical that aircraft spraying be done effectively. Nothing is as expensive or as high profile as this type of treatment, and even in mosquito control operations that do a lot of it, efficient use of this tool is of utmost importance. FieldSeeker® GIS software for mosquito and vector control, helps districts manage these important […]

How to get an AutoCAD Drawing into TerraSync as Background File

During the course of providing training for our customers who purchase a GNSS mapping system, we often get asked, “How do I get my AutoCAD drawing into TerraSync?” Depending on how AutoCAD is used, the drawing could have a known spatial reference or it could have an arbitrary coordinate system defined as the lower left […]

High Accuracy GNSS in Today’s Common GIS Workflows

Today’s field users and GIS folks now have more choices than ever regarding tools for field data collection. It makes sense that collecting data in the field is relatively easy given all these choices and the ability to use common devices like phones and tablets. Add in geopdf viewers and simple to use apps for […]

Differential Correction Sources: SBAS, RTK Base Stations, and Real-time GNSS Networks

We get a lot of questions about how to improve in-the-field accuracy with GNSS equipment.  Many new or less-experienced users suspect that when a device is marketed to provide 10 cm or 1 cm level accuracy, that it provides that right out of the box.  When you pay a pretty penny for a high-end machine […]

The New Trimble R1 GNSS Receiver is Small but Powerful

Smart devices such as iPads and Android tablets are becoming more and more popular for collecting GIS data in the field.  They are affordable, readily available, and powerful and offer benefits that GIS folks like such as a larger view for displaying imagery and completing an attribute form.  The “tablet craze” as you might call […]

Determining and Defining Coordinate Systems in ArcGIS

ArcGIS Toolbox – Define Projection vs. Project   –  What’s the difference? Well the difference is very important.  If you’ve tried to add a shapefile into ArcMap that does not have a .prj file (Projection File), you will get the message that it has an Unknown Spatial Reference.  Sometimes you will get lucky and have a […]

Satellites Galore! What We Launch Into Space and GPS Modernization

Today there are hundreds of satellites orbiting Earth.  A portion of those are Global Navigation Satellite Systems (GNSS) like GPS (USA), GLONASS (Russia), Galileo (European Union), and COMPASS or BeiDou (China).  But there are many other reasons governments and commercial interests want to put birds in the sky: imagery capture, communications, television broadcasting, weather monitoring, intelligence […]
